RE: [Linux-cluster] lv and its snapshot can be mounted at the same timein one node?



If I just used lvm2 and ext3, without cluster suite and GFS, I found that
I can mount the lv and its snapshot at the same time.

I just want the file system supports two features as below, but can't be
found now.

					   Extended on mounted
its snapshot can be mounted at the same time

Ext3						not support
support
XFS							support
not support
Cluster suite/GFS			support
???

Is that Cluster suite/GFS can support feature of the snapshot mounted at the
same time above?

Thanks.

Operations of ext3 fs just listed below:

#pvcreate /dev/sda /dev/sdb

#vgcreate vg1 /dev/sda /dev/sdb

#lvcreate -L 10G -n lv1 vg1

#mke2fs /dev/vg1/lv1

#mount /dev/vg1/lv1 /home/lv1

#lvcreate -s -L 2G -n snap1 /dev/vg1/lv1

#mount -o ro /dev/vg1/snap1 /home/snap1
	*** It is OK! ***
